2GHz Wi-Fi frequently cannot obtain IP address
Hello,
I have AX6600 (GX90) router and AC1900 (RE550) range extender to build an OneMesh network at my home. I purchased these two devices about one week ago. Today I noticed that, several wireless devices have trouble connecting to router. They kept saying “obtaining IP address” and eventually failed to connect to the router.
Checking the status on http://192.168.0.1 , the device seems being given an IP address by the router, but it won’t connect to the router. There are only total ~10 devices connected to the router at that time. It only happens on the 2.4ghz wifi network, not 5ghz. It happened to my Huawei phone, XiaoMi phone and Amazon echo show. After I reboot the router, those devices can connect to 2.4ghz wifi for a short amount of time, then they will lose the connection to the router again.
What can I do to solve this issue? Thanks for the help in advance.
